Statistical analyses of effects of pretreatments on self-administration of DTG as shown in Fig. 5

Comparisons were made in the response rates of responses on the active lever maintained during each component compared with corresponding components after pretreatments with saline using a two-way repeated-measures ANOVA followed by post hoc Bonferroni t tests. The post hoc results are shown only if effects were statistically significant. The Δ values, in responses/second, were calculated as a subtraction of response rates maintained by cocaine after pretreatment with the BZT analog from those obtained after saline pretreatment.
